2026秋人教版九年级上册 Unit1 The Changing World语法讲义 一般过去时与现在完成时对比 + used to结构 1.一般过去时与现在完成时的对比 1、基本用法 一般过去时：描述过去某个时间发生的动作、存在的状态，和现在没有关系。 现在完成时：过去发生的动作对现在产生影响、造成结果；也可以表示动作从过去一直持续到现在。 一般过去时 用法：过去动作或状态，与现在无关 时间状语：yesterday, last week, in 2017, ago 例句：He became a good friend of your grandfather 20 years ago. 现在完成时 用法：过去动作对现在有影响或持续到现在 时间状语：already, yet, ever, never, for, since 例句：They haven’t seen each other for ages! 2、常用结构 一般过去时：主语 + 动词过去式 + 其他 例句：I visited the museum yesterday. 现在完成时：主语 + have/has + 过去分词 + 其他 例句：I have visited the museum twice. 3、常考考点 1.一般过去时常搭配明确的过去时间状语；现在完成时不能搭配具体过去时间。 2.现在完成时侧重强调对现在的影响或者动作持续；一般过去时只客观陈述过去发生的事实。 3.already多用于肯定句；yet多用于否定句、疑问句。 4、拓展 现在完成时可以表达经历：I have been to Shanghai.（我去过上海） 一般过去时可以和used to搭配：He used to be shy. 2.used to 结构 1、基本用法 含义：过去常常做某事，但是现在已经不再这样，后面接动词原形。 2、常用结构 肯定句型：主语 + used to +动词原形 例句：The hills used to be covered with sand. 否定句型：主语 + didn’t use to +动词原形 / 主语 + used not to +动词原形 例句：They didn’t use to have a supermarket. 疑问句型：Did +主语 + use to +动词原形？ 例句：Did you use to live here? 3、常考考点 1.used to do 和 be used to doing区分：used to do 过去常常；be used to doing 习惯于。 2.used to 和 would区分：would后面不能接状态动词（be, have, like）。 4、拓展 现在完成时与used to可以连用：I have changed a lot since I used to live there.
